PCB-GCode Phorum

Pcb-gcode lets you use your milling machine, router, engraver, etc. to make printed circuit boards without using toxic chemicals. You create your design with Eagle, then use pcb-gcode to create g-code, which you run on your machine. Your machine cuts around the traces for the circuits. pcb-gcode also creates drill files to drill holes, mill files to cut the board out, or make cutouts in the board. You can also create files to engrave text on the boards, such as your copyright, component names, etc. PCB-GCode has been free since 2003, but if you find the software useful, donations of any amount are greatly appreciated.
